The following guidance supplements that Bulletin and is organized
according to the section name of the National Register registration
form.

NAME OF PROPERTY

The historic name of aviation properties will be used to identify
it in the National Register files, the computerized National Register
Information System (NRIS), and any publications. If there is more
than one historic name for a facility, enter the name that best
reflects the significance of the property; enter other historic
or different names under "other names."

CLASSIFICATION

Intact aircraft are classified as "structures"; aviation
wrecks are either structures or "sites." Other examples
of structures are navigation beacons and seaplane ramps. A single
air-related facility (such as a hangar, a terminal building, or
a control tower) is a "building." An air-related facility
with a combination of buildings, sites, structures, or objects is
a "district." Refer to National
Register Bulletin: How to Complete the National Register Registration
Form for definitions and additional examples.

National Register Bulletin: How
to Complete the National Register Registration Formincludes a list of historic functions that should be consulted
to define both the historic and present uses of the historic aviation
property. Only the most predominant functions of the property should
be listed. Functions that may apply to historic aviation properties
could include: "domestic" (for institutional housing on
an air base); "commerce/trade" (for an air-related facility
associated with commercial endeavors); "social" (for an
air-related facility containing an important recreation hall); "education"
(for air-related educational institutions); "industry"
(for aircraft manufacturing plants); "defense" (for aircraft,
air base, missile launching sites); and "transportation"
(for aircraft, hangars, airports, launching sites).

DESCRIPTION

In this section provide a narrative describing the current and
historic appearance and condition of the historic aviation property.
The narrative should begin with a summary paragraph that briefly
describes the property, noting its major physical characteristics
and assessing its overall integrity. Additional paragraphs describing
the aviation property should support the summary paragraph.

In describing aircraft, use official designations:

. Manufacturer's designation

. Constructor's number

. Civil or military registration number

. Civil or military designation of type or class

. Aircraft's configuration sequence

. Type model number

. Status prefix letters

. Special purpose suffix letters

. Mission designation

. Serial number for the specific aircraft

. Appropriate designations for major components,like engines,propellers,
and landing gear, and the manufacturers of the major components

For aircraft, the Description Section should address the following:

. When was the aircraft constructed?

. What are the aircraft's historic characteristics?

. What were the historical influences (such as design, materials,
style or function) on the aircraft's appearance?

. What modifications, major repairs, alterations, and other changes
have been made over time and when? How have these changes (other
than routine maintenance that replaces existing parts in kind) affected
the aircraft's integrity?

. What is the current condition of the aircraft, including exterior
and interior features?

STATEMENT OF SIGNIFICANCE

The Statement of Significance is a narrative that describes why
the historic aviation property was important by explaining how the
property relates to its historic context, National Register criteria,
and areas and periods of significance. The important events and
persons, design qualities, or information potential associated with
the property are discussed. The Statement of Significance should
begin with a summary paragraph describing the overall importance
of the aviation property and should be followed with additional
paragraphs supporting the significance of the property and its associated
important events and people.

The Statement of Significance should address:

. How the property meets one or more of the National Register criteria

. Do any of the National Register criteria considerations apply
to the property?

. What are the areas of significance with which the property is
associated?

. What is the property's period of significance?

. Who are the leading individuals associated with the property
and what was their role in the property's history?

. Architecture: air-related facilities which are good representatives
of a type, period, or method of construction; or that represent
the work of a master; or that possess high artistic value; or that
represent a significant and distinguishable entity whose components
may lack individual distinction.

. Archeology: aircraft (or aviation wrecks) and air-related facilities
that have yielded or may be likely to yield information important
in the history of aircraft design, production, maintenance or operation.

. Engineering: aircraft, manufacturing plants, or research facilities
important for aviation technological developments, or aircraft significant
for their engineering characteristics.

. Entertainment/Recreation: aircraft used for leisure activities,
diversion, amusement, or sport, and aircraft plants associated with
the production of civilian recreational aircraft, as well as properties
used in recreational aviation activities.

. Industry: manufacturing plants associated with the production
of aircraft and aircraft

components.

. Invention: aircraft or air-related facilities associated with
the invention or refinement of aircraft design.
